Waste and wastewater treatment and recycling system

ABSTRACT

A waste and wastewater treatment and recycling system separates blackwater and greywater at their respective sources and includes a waste separation system for decomposing the blackwater into water vapor and carbon dioxide gas, a wastewater treatment system for circulating, aerating, and separating the greywater into precipitated solid matter and treated water, and a filtration, disinfection, and water recycling system for filtering and disinfecting the treated water to form recyclable water. The precipitated solid matter is transferred to the waste separation system and the recyclable water is passed through a membrane filtration system to form potable water. A monitoring system monitors and controls operation of the waste separation system, the wastewater treatment system, and the filtration, disinfection, and water recycling system.

BACKGROUND OF THE INVENTION

The present invention relates generally to a system for treating and recycling waste and wastewater, and more particularly to a system which separates blackwater and greywater at their respective sources, decomposes and converts the blackwater into water vapor and carbon dioxide gas, circulates, aerates, and separates the greywater into precipitated solid matter and treated water, and filters and disinfects the treated water to form recyclable and potable water.

Wastewater generated by a household is typically classified as either blackwater or greywater. Blackwater includes water and organic waste drained from toilets and garbage disposals. Greywater includes wastewater drained from bathtubs, showers, sinks, clothes washers, and dishwashers. Typically, blackwater and greywater are plumbed into one single wastewater stream and directed to a septic or sewage system. By combining blackwater and greywater into one single wastewater stream, however, the entire wastewater stream must be treated as blackwater. Because water pollution and water availability have become increasingly important both nationally and internationally, numerous attempts have been made to treat organic waste and wastewater to acceptable levels and standards for reuse. Such attempts, however, have not produced environmentally benign and safe-for-recycle end-products.

Accordingly, a need exists for a system which separates blackwater and greywater at their respective sources and treats these two wastewater streams individually within separate processing systems to ensure that organic waste and wastewater from both streams are converted into environmentally benign and safe-for-recycle end-products.

SUMMARY OF THE INVENTION

One aspect of the present invention provides a waste and wastewater treatment and recycling system including a waste separation system, a wastewater treatment system, and a filtration, disinfection, and water recycling system.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. The following detailed description, therefore, is not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.

FIG. 1 illustrates one embodiment of a waste and wastewater treatment and recycling system 10 according to the present invention. System 10 includes a waste separation system 100, a wastewater treatment system 200, a filtration, disinfection, and water recycling system 300, and a monitoring system 400. System 10 separates, treats, and recycles organic waste 12 and wastewater 14, in the form of blackwater and greywater, respectively, into environmentally benign and safe-for-recycle end-products. Blackwater is defined to include human toilet and kitchen organic wastes, and greywater is defined to include wastewater which has been used for domestic activities such as personal hygiene, clothes washing, and dishwashing.

In one embodiment, system 10 is configured for use in a dwelling 20 which includes a first group of appliances which generate greywater and a second group of appliances which generate blackwater. The first group of appliances includes, for example, a bathtub and/or shower 22, a sink 24, a dishwashing machine 26, and a clothes washing machine 28. The second group of appliances includes, for example, toilets 30 a and 30 b, and a garbage disposal 32. As such, toilets 30 a and 30 b, and a garbage disposal 32 are plumbed separately from bathtub and/or shower 22, sink 24, dishwashing machine 26, and clothes washing machine 28. By separately plumbing the first group of appliances and the second group of appliances, blackwater and greywater are separated at each of their respective sources. Thus, system 10 does not commingle blackwater with greywater.

In an illustrative embodiment, toilets 30 a and 30 b utilize little or no water for flushing, and garbage disposal 32 incorporates a water-conserving faucet and sink arrangement. Toilet 30 a, for example, is a waterless or low water-use gravity flush-type toilet and toilet 30 b, for example, is a vacuum flush-type toilet. An example of toilet 30 a is a Traveler 500, 900, or 2000 series toilet manufactured by SeaLand Technology, Inc. or a STW series Pearl Foam Flush-Type toilet manufactured by Nepon and an example of toilet 30 b is a 500, 800, or 1000 series Vacu-Flush toilet manufactured by SeaLand Technology, Inc.

Since system 10 essentially establishes a closed-loop, zero discharge system, dwelling 20 includes a cistern 40 which forms a backup reservoir 42. Backup reservoir 42 supplies additional water to system 10 to makeup for water lost from drinking, cooking, toilet flushing, and/or delivery of organic waste 12 to waste separation system 100. In one embodiment, cistern 40 collects rainwater via conduit 44, and/or receives water from a well or municipal source via conduit 45. Pre-filters 46 and 47 are provided in conduits 44 and 45, respectively, for filtering the water before entering backup reservoir 42. Valves 48 and 49 are provided in conduits 44 and 45, respectively, for communicating conduits 44 and 45 with backup reservoir 42. Valves 48 and 49 each include a sensing device 48 a and 49 a, respectively, which senses a level of water within cistern 40 and opens or closes valves 48 and 49 accordingly. Cistern 40 communicates with wastewater treatment system 200 via a conduit 50 such that water from backup reservoir 42 is combined with wastewater 14. A check valve 52 is provided in conduit 50 to prevent backflow of water through conduit 50. A pump 54 communicates with conduit 50 and draws water from backup reservoir 42 to add water to the closed-loop, zero discharge system.

While system 10 is illustrated for use in dwelling 20, it is within the scope of the present invention for system 10 to be a self-contained system which is portable and/or capable of being buried in a vault. In addition, it is also within the scope of the present invention for system 10 to be used in marine and space environments wherein discharge of blackwater and/or greywater is not environmentally acceptable.

As illustrated in FIG. 2, waste separation system 100 includes a composting vessel 110, at least one organic waste agitator 130, at least one compost conveyor 140, and a liquid distribution system 150. Waste separation system 100 facilitates aerobic decomposition and composting of organic waste 12 transported thereto. Aerobic decomposition is defined to include decomposition in the presence of air and oxygen. In one embodiment, composting vessel 110 is a single or double-walled, insulated vessel and defines a compost chamber 112 which receives and decomposes organic waste 12 into primarily water vapor and carbon dioxide gas. In addition to water vapor and carbon dioxide gas, a relatively small volume of decomposed material, which can be readily handled, for example, as a garden fertilizer or the like, is also produced.

Compost chamber 112 includes an upper waste receiving volume 112 a which receives organic waste 12, a central mixing and aeration volume 112 b in which organic waste 12 is mixed and aerated, and a lower composting and compost collection volume 112 c wherein decomposed material eventually settles. Organic waste 12 includes discharge from a variety of components, including toilets 30 a and 30 b, and garbage disposal 32, as well as other organic materials such as leaves, paper, garbage, and/or wood shavings or the like. It is, however, within the scope of the present invention for waste separation system 100 to handle biological waste materials from sources other than those enumerated.

In one embodiment, composting vessel 110 includes an upper section 114 and a lower section 116. Upper section 114 and lower section 116 are joined together at mating flanges 114 a and 116 a, respectively, to form compost chamber 112. Upper section 114 includes a top wall 114 b and a pair of side walls 114 c, and lower section 116 includes a bottom wall 116 b and a pair of side walls 116 c. One of the side walls 114 c of upper section 114 has an opening 114 d defined therein in which an openable and/or removable hatch 115 is fitted. Opening and/or removal of hatch 115 facilitates access to compost chamber 112 for maintenance, charging with bulk organic material, and/or removal of decomposed material. Formation of composting vessel 110 from upper and lower sections 114 and 116, respectively, facilitates transport and assembly. In addition, a size of upper and lower sections 114 and 116, respectively, varies depending primarily on an amount of organic waste 12 to be processed by system 10. While composting vessel 110 is illustrated as being of rectangular shape, it is within the scope of the present invention for composting vessel 110 to be cylindrical in shape.

In one embodiment, composting vessel 110 includes a perforated basket 118 suspended above bottom wall 116 b of lower section 116 and spaced from sidewalls 116 c of lower section 116. In one embodiment, perforated basket 118 includes a perforated floor 118 a and perforated sidewalls (not shown). Perforated basket 118 facilitates aeration of organic waste 12 disposed within compost chamber 112 by permitting air to flow under, through, and around organic waste 12. Since perforated basket 118 is suspended within compost chamber 112, air circulation occurs throughout lower composting and compost collection volume 112 c and central mixing and aeration volume 112 b. In addition, water and/or other liquids accompanying organic waste 12 drain through perforated floor 118 a to bottom wall 116 b for removal by liquid distribution system 150, as described below.

Composting vessel 110 has an air inlet 120, an exhaust outlet 122 and at least one waste inlet 124 defined therein. Air inlet 120, exhaust outlet 122, and waste inlet 124 each communicate with compost chamber 112. In one embodiment, air inlet 120, exhaust outlet 122, and waste inlet 124 are each formed in top wall 114 b of upper section 114. In addition, an exhaust fan 126 communicates with exhaust outlet 122. Furthermore, compost chamber 112 is divided by a front baffle 128 and a rear baffle 129 such that exhaust outlet 122 is separated from air inlet 120 by front baffle 128. Front baffle 128 is spaced from bottom wall 116 b of lower section 116 to facilitate airflow thereunder. Front baffle 128 includes a door 128 a which facilitates access to innermost portions of composting vessel 110, including upper waste receiving volume 112 a and central mixing and aeration volume 112 b. Rear baffle 129 has a lower opening 129 a and an upper opening 129 b defined therein which facilitate airflow therethrough.

Exhaust fan 126 draws air in air inlet 120, through compost chamber 112, and out exhaust outlet 122 such that air flows, as illustrated by arrows 101, along front baffle 128, under front baffle 128, through, under, and around perforated basket 118, through and under perforated floor 118 a, through lower and upper openings 129 a and 129 b, respectively, and out exhaust outlet 122. As such, air flows beneath, around, and through lower composting and compost collection volume 112 c, central mixing and aeration volume 112 b, and upper waste receiving volume 112 a to aerate compost chamber 112 and disperse water vapor and carbon dioxide gases generated within composting vessel 110 during decomposition to the atmosphere.

In one embodiment, waste inlet 124 includes a toilet waste inlet 124 a, a kitchen waste inlet 124 b, and a sludge inlet 124 c. Toilet waste inlet 124 a communicates with toilets 30 a and 30 b via conduits 34 a and 34 b (FIG. 1), respectively, kitchen waste inlet 124 b communicates with garbage disposal 32 via a conduit 36 (FIG. 1), and sludge inlet 124 c communicates with wastewater treatment system 200, as described below, via a conduit 38 (FIG. 1). While waste inlet 124 is illustrated as communicating with toilets 30 a and 30 b, and garbage disposal 32, it is within the scope of the present invention for any arrangement and/or number of sources to provide organic waste 12 to waste separation system 100. In addition, conduits 34 a, 34 b, 36, and 38, as well as all other conduits described herein, are preferably formed of polyvinylchloride (PVC), although it is within the scope of the present invention for various other natural and synthetic pipe compositions known to those skilled in the art to be employed.

Agitator 130 is positioned within compost chamber 112 below waste inlet 124 and upper waste receiving volume 112 a in central mixing and aeration volume 112 b. In one embodiment, agitator 130 is an elongated rod 132 which includes a plurality of tines 134 protruding radially therefrom. Tines 134 are spaced along a length of elongated rod 132 in an offset manner so as to be oriented in a noncoplanar arrangement around elongated rod 132. Elongated rod 132 is rotatably mounted within composting vessel 110 and rotated by a motor 136. As such, tines 134 agitate and mix organic waste 12 disposed within central mixing and aeration volume 112 b of compost chamber 112. Such mixing facilitates aerobic biological decomposition of organic waste 12. While elongated rod 132 is illustrated as being rotated by motor 126, it is within the scope of the present invention for elongated rod 132 to be rotated by a hand.

Conveyor 140 is positioned within compost chamber 112 below agitator 130 and central mixing and aeration volume 112 b in lower composting and compost collection volume 112 c above perforated floor 118 a. Conveyor 140 facilitates removal of decomposed material derived from organic waste 12 and collected within lower composting and compost collection volume 112 c by transferring decomposed material to a compost collection area 142 formed along bottom wall 116 b of lower section 116. In one embodiment, conveyor 140 is a screw-type auger 144 rotatably mounted within composting vessel 110. As such, auger 144 is rotated by, for example, a mechanical arrangement and/or hand, to transfer decomposed material collected within lower composting and compost collection volume 112 c to compost collection area 142. Thereafter, decomposed material is removed from composting vessel 110 by access through opening 114 d.

During selected uses, water and/or other liquids may be transported into compost chamber 112 through, for example, waste inlet 124. These liquids will tend to settle toward bottom wall 116 b of lower section 116 and collect within a liquid collection area 152 formed along bottom wall 116 b. Since perforated floor 118 a is suspended above bottom wall 116 b, perforated floor 118 a allows liquid to pass through organic waste 12 to liquid collection area 152. As such, liquid distribution system 150 disperses and/or evaporates liquid collected within liquid collection area 152.

Liquid distribution system 150 includes a liquid circulation arrangement 154, a liquid dispersion system 156, and a liquid evaporation system 158. In one embodiment, liquid circulation arrangement 154 includes a pump 160 communicating with liquid collection area 152 and a distribution conduit 162 communicating with pump 160 to form a liquid distribution flow path. Pump 160 includes a sensing device 161 which activates and deactivates pump 160, according to a level of liquid collected within liquid collection area 152, to draw liquid from liquid collection area 152. While bottom wall 116 b is illustrated as being flat, it is within the scope of the present invention for bottom wall 116 b to include a slanted or recessed portion which directs liquid into liquid collection area 152 for dispersion and/or evaporation by liquid distribution system 150.

Liquid dispersion system 156 maintains a moist environment throughout compost chamber 112 so as to facilitate biological processes which lead to decomposition. In one embodiment, liquid dispersion system 156 includes a dispersion conduit 164 communicating with distribution conduit 162 and a dispersion arrangement 166 communicating with dispersion conduit 164. A valve 165 is provided in dispersion conduit 164 to selectively direct liquid through dispersion conduit 164 to dispersion arrangement 166. In one embodiment, dispersion arrangement 166 includes an aperture or a plurality of apertures in the form of a nozzle 167 which communicates with dispersion conduit 164. A plurality of apertures or nozzles 167 are positioned above agitator 130 and central mixing and aeration volume 112 b so as to disperse collected liquid, under pressure, throughout upper waste receiving volume 112 a and into central mixing and aeration volume 112 b. Thus, liquid dispersion system 156 ensures that organic waste 12 does not dry out to an extent likely to inhibit decomposition.

Liquid evaporation system 158 dissipates liquid collected within liquid collection area 152. In one embodiment, liquid evaporation system 158 includes an evaporation conduit 170 communicating with distribution conduit 162 and an evaporation arrangement 172 communicating with evaporation conduit 170. A valve 171 is provided in evaporation conduit 170 to selectively direct liquid through evaporation conduit 170 to evaporation arrangement 172. In one embodiment, evaporation arrangement 172 includes an aperture or nozzle 173 communicating with evaporation conduit 170. Aperture or nozzle 173 communicates with exhaust outlet 122 so as to disperse collected liquid, under pressure, into exhaust outlet 122. Thus, dispersed liquid comes into contact and is carried out of composting vessel 110 with air that is drawn through exhaust outlet 122 by exhaust fan 126.

It is noted that relatively little water is to be used with waste separation system 100, and that large volumes of free-standing water are generally avoided in composting arrangements. Thus, liquid dispersion system 156 and liquid evaporation system 158 disperse and/or evaporate liquid that does collect within liquid collection area 152. Should an excessive amount of liquid collect within liquid collection area 152, liquid circulation arrangement 154 directs liquid outwardly from composting vessel 110.

In one embodiment, a control unit 180 controls operation of exhaust fan 126, motor 136 and agitator 130, and pump 160. It is, however, within the scope of the present invention for control unit 180 to also control conveyor 140 and valves 165 and 171. In addition, a service light 182 is provided within composting vessel 110.

Composting vessel 110 is initially charged with a large volume of wood shavings, soil, leaves, paper, and/or other organic material, including microbial material, for establishing decomposition. Over time, additional organic material is added to these initial charges through door 128 a and from, for example, toilets 30 a and 30 b, and garbage disposal 32. After an extended period of time, during which there is an occasional mixing of composting material and/or addition of further nutrient and/or charging material to composting vessel 110 to facilitate aerobic processes therein, a substantial amount of substantially decomposed material collects in lower composting and compost collection volume 112 c of compost chamber 112. After that time, and periodically from then on, conveyor 140 is operated to discharge decomposed material to compost collection area 142, wherefrom it is readily removed. In a typical operation with one toilet and one garbage disposal, initial operation of composting vessel 110 may be for several years before a first discharge operation is necessary. During such time, agitator 130 need only be turned gently every few months or so, for efficient operation.

As illustrated in FIGS. 3A and 3B, wastewater treatment system 200 includes a surge tank 210, an aeration tank 220, a clarification tank 230, an extended aeration system 240, and a sludge removal system 280. Surge tank 210, aeration tank 220, and clarification tank 230 define a surge chamber 212, an aeration chamber 222, and a clarification chamber 232, respectively. In one embodiment, surge tank 210, aeration tank 220, and clarification tank 230 each have an inlet 210 a, 220 a, 230 a, respectively, and an outlet 210 b, 220 b, 230 b, respectively, defined therein. In addition, surge tank 210, aeration tank 220, and clarification tank 230 each have a sloped floor 210 c, 220 c, and 230 c, respectively. It is, however, within the scope of the present invention for surge tank 210, aeration tank 220, and clarification tank 230 to each have a flat floor.

In one embodiment, inlet 210 a of surge tank 210 communicates with a drain of bathtub and/or shower 22, a drain of sink 24, a drain of dishwashing machine 26, and a drain of clothes washing machine 28 via a conduit 39 (FIG. 1). Thus, inlet 210 a constitutes a wastewater inlet of wastewater treatment system 200. Outlet 210 b of surge tank 210 communicates with inlet 220 a of aeration tank 220 via a conduit 214 and outlet 220 b of aeration tank 220 communicates with inlet 230 a of clarification tank 230 via a conduit 224. In addition, outlet 230 b of clarification tank 230 communicates with filtration, disinfection, and water recycling system 300, as described below, via a conduit 234. Thus, outlet 230 b constitutes a treated water outlet or effluent line of wastewater treatment system 200.

In one embodiment, surge tank 210, aeration tank 220, and clarification tank 230 communicate in-line so as to provide gravity flow of water therethrough. Thus, conduit 234 is positioned lower than conduit 224, conduit 224 is positioned lower than conduit 214, and conduit 214 is positioned lower than conduit 39. Conduit 224, however, includes an extension 224 a extending downward into aeration chamber 222 to prevent direct through-flow of water between aeration tank 220 and clarification tank 230. In addition, conduit 234 includes an extension 234 a extending downward into clarification chamber 232 to prevent direct through-flow of water between clarification tank 230 and filtration, disinfection, and water recycling system 300. In one embodiment, a filter 236 is provided in extension 234 a to filter water passing through conduit 234 to filtration, disinfection, and water recycling system 300. An example of filter 236 is an A1800 filter manufactured by Zabel.

As illustrated in FIG. 3A, extended aeration system 240 includes an air delivery system 242 and an airflow array 244 for water circulation, distribution, and aeration within and amongst surge tank 210, aeration tank 220, and clarification tank 230. In one embodiment, air delivery system 242 includes a pump 246 and a valve arrangement 248. Pump 246 generates a supply of pressurized air and valve arrangement 248 includes a plurality of valves 249 which provide selective delivery and adjustment of pressurized air to airflow array 244. In one embodiment, airflow array 244 includes an airlift 250 communicating with surge chamber 212, an airlift 254 communicating with aeration chamber 222, an airlift 258 communicating with clarification chamber 232, and an airlift 262 communicating with surge chamber 212. In addition, airflow array 244 includes an air diffuser 270 communicating with surge chamber 212 and an air diffuser 274 communicating with aeration chamber 222. Airlifts 250, 254, 258, and 262, as well as air diffusers 270 and 274 are air assisted systems which facilitate water circulation, distribution, and aeration within and amongst surge tank 210, aeration tank 220, and clarification tank 230.

Airlifts 250, 254, 258, and 262 provide circulation and distribution of water within and amongst surge tank 210, aeration tank 220, and clarification tank 230. Airlift 250 includes an air delivery conduit 251 communicating with one of the valves 249 and an airlift conduit 252 communicating with air delivery conduit 251. Airlift conduit 252 extends into surge chamber 212 so as to draw water from a bottom portion of surge chamber 212 and redistribute the water to a top portion of surge chamber 212 as illustrated by arrows 253. Thus, airlift 252 circulates water contained within surge tank 210. Airlift 254 includes an air delivery conduit 255 communicating with one of the valves 249 and an airlift conduit 256 communicating with air delivery conduit 255. Air lift conduit 255 extends into aeration chamber 222 so as to draw water from a bottom portion of aeration chamber 222 and redistribute the water to a top portion of aeration chamber 222 as illustrated by arrows 257. Thus, airlift 254 circulates water contained within aeration tank 220. Airlift 258 includes an air delivery conduit 259 communicating with one of the valves 249 and an airlift conduit 260 communicating with air delivery conduit 259. Airlift conduit 260 extends into clarification chamber 232 so as to draw water from a bottom portion of clarification chamber 232 and redistribute the water to the top portion of surge chamber 212 as illustrated by arrows 261. Thus, airlift 258 returns settled solids back to surge tank 210 for additional treatment. Airlift 262 includes an air delivery conduit 263 communicating with one of the valves 249 and an airlift conduit 264 communicating with air delivery conduit 263. Airlift conduit 264 extends into surge chamber 212 so as to draw water from above the bottom portion of surge chamber 212 and redistribute the water to the top portion of aeration chamber 222 as illustrated by arrows 265. Thus, airlift 262 maintains a lower level of water in surge tank 210 than in aeration tank 220.

Air diffusers 270 and 274 provide aeration of water contained within surge tank 210 and aeration tank 220, respectively. Air diffuser 270 includes an air delivery conduit 271 communicating with one of the valves 249 and a diffuser head 272 provided at an end of air delivery conduit 271. Diffuser head 272 is submerged within surge chamber 212 so as to aerate water contained therein. Thus, air diffuser 270 provides oxygen for aerobic biological treatment of water contained within surge tank 210. Air diffuser 274 includes an air delivery conduit 275 communicating with one of the valves 249 and a diffuser head 276 provided at an end of air delivery conduit 275.

By separating blackwater and greywater at each of their respective sources, and then transporting and treating these two wastewater streams individually within separate processing systems, the present invention ensures that organic wastes and wastewater from both streams are converted to environmentally benign and safe-for-recycle end-products. To ensure that the separate processing systems operate appropriately, a monitoring system collects data, controls operations, reports any operational discrepancies, and shuts down the processing systems in case of a malfunction.
